Clinical information about diverticulitis:

Diverticula are pockets that can develop inside the colon, a condition known as diverticulosis. While it's common for these pockets to form as people age, they typically don't cause any problems. However, when these pockets become infected and inflamed, it leads to diverticulitis, which can cause acute or chronic pain. Fortunately, diverticulitis is generally treatable and can be easily healed. However, in some cases, complications such as scarring, perforations, or the development of abscesses may occur.

A person with diverticulitis will likely have the following symptoms:

• They will feel severe pain in their abdomen
• They will likely become constipated or have diarrhea
• They will bleed from their rectum (which can also be the result of constipation)
• They will have fevers or feel feverish, and they will feel nauseated and sometimes vomit

• Hemorrhage of small intestine due to diverticulitis
• Diverticulitis of large intestine with complication
